' IMPROVEMENT IN ATTACHING DEVICES FOR LEATHER STRAPS.

Specification forming part of Letters Patent N0. 196,939, dated November 6, 1877 application led July 14, 1877.

To all whom it may concern:

Be it known that I, Trroivms HOXEY SABIN, of Green Centre, in the county of Noble and State of Indiana, have invented certain new:

and useful Improvements in Corrugated Harness Attachments, of which the following is a specification My invention relates to the sn ap-hooks and other hooks and metal loops or appurtenances used on harness 5 and it consists in the construction and combination of corrugated clamping-plates for the purpose of securing said hooks or other appurtenances firmly upon the ends of the straps to which they belong, substantially as hereinafter more fully described, and pointed out in the claim.

In the drawing, Figure l is a plan view. Fig. 2 is a side view of the portion of aleather strap with a snap-hook affixed to its end. Fig.

3 is a longitudinal section on the linea@ x, Fig.`

l 5 and Fig. et is a cross-section.

Similar letters of reference indicate corre` sponding parts in all the gures.

A is the strap. B is the hook, and C C the clamping-plates by means of which it is secured upon the end of the strap. The hook B, with its spring` b, is riveted onto the top plate O, which. iits between the flanges c c ofV the other plate, O. The inner sides or faces of plates O and C are corrugated, as shown in Fig. 3, the corrugations taking the form of steps or shoulders, the steep sides of which face the front ends of the plates, from which they slant down rearwardly. When the strap A is placed between the two plates, and these are united by the screws fa a, the strap will bev rmly held or clamped between the corrugated siu'faces of plates O and C', the steep shoulders of which, as Will be seen by reference to Fig. 3, absolutely prevent the withdrawal of the strap. The iianges c of the lower plate prevent the strap from being displaced laterally.

By the ordinary method of securing hooks and othermetallic harness appurtenances to the ends of strapsi. e., by simply riveting them onto the fastening-plates, or securing them between two smooth surfaces with the aid of perforations and screws-all the strain comes upon the perforations in the strap, which, by the constantpull, become elongated, and finally tear out, necessitating repair of the strap or Aits replacement by a new one; but by my improvement the strap is held in place by friction between the corrugated plates, thus making tearing or displacement impossible.

I do not, broadly, claim corrugated clamping-plates, as I am aware that they are not new; but,

Having thus described my invention, I'claim and desire to secure by Letters Patent of the United States- The combination, with the side-iianged bot- I THOMAS HOXEY SABIN.
